Kar98K Upon Touchdown! - Chapter 700 - Looking Out For Your Neighbor!

There was a Senior Brother and a Junior Sister. One of them was transmigrated to this world and had cheats while the other was the reincarnation of a Great Emperor.

The amiable looking patriarch is gazing at a stone monkey: “Wukong, what do you want to learn from me?” “It’s all up to master’s instruction.” The stone monkey respectfully replied: “As long as I will be able to beat up Tathagata, then it’s alright.” One hundred years later, the stone monkey defeated Tathagata and ascended the throne, becoming the Jade Emperor.
